yes,
sorry about the major delays, iv been getting smashed with school and trade school and what ever else.
just to make sure everyone is aware the manifolds will fit with a standard inlet manifoldbut im now back at school so i have a fair bit of spare time on computers.
i am going to be redesigning and making two different manifolds only because of the interest i have has so far with the first design. The first manifold does have a divider between the collector,the way it was fabricated is with a weebbing in the middle joining the two pipes to the diameter of the t25 flange. (will provide pics)

i am also going to be making some up with all 4 pipes meeting at the collector as D has suggested although these will be of higher expence as there is more fabricating and time required (price yet to be confirmed)

just waiting on the pressure pipe bends so fabrication will begin as soon a possible
1000 manifolds will be on the way very soon have already sorted out a design and it will be similar to a top mount.
thanx Dan
